As an ISO 9001-certified cutting tool specialist since 2009, we supply precision HSS end mills to 30+ countries worldwide.
HSS End Mills (High-Speed Steel Milling Cutters)
Engineered for CNC machining centers and manual mills, our high-speed steel end mills deliver optimal performance on ferrous and non-ferrous metals. Compared to carbide end mills, HSS tools provide better cost-efficiency for medium-volume production.
Technical Specifications:
Material Grades:
- M2/M35 (DIN/ANSII certified)
- HSS-Co8 (8% cobalt content)
- HSS-E (Vanneadium enhanced)
Size Range:
- Diameter: 0.5-25mm (custom sizes available)
- Flute Length: 2xD to 10xD
Coatings:
- Zinn (gold): 600°C rating
- TiAlN (purple): 800°C rating
- TiCN (gray): Best for stainless steel
Core Performance Advantages:
1 Extended Tool Life
Cobalt-alloyed HSS demonstrates 50% longer lifespan than standard high speed steel in our ASTM G65 abrasion tests.
2 Multi-Flute Configurations
Choose from:
- 2-flute: Best for aluminum milling
- 4-flute: Ideal for steel finishing
- 6-flute: Mirror finishes on alloys
3 Thermal-Resistant Coatings
Our proprietary coating technology reduces cutting temperature by 15-20% compared to standard coatings.
Industry Applications：
- Automotive: Engine block machining (Case Study: Reduced cycle time by 22% for BMW supplier)
- Aerospace: Titanium aircraft components
- Mold & Die: P20 steel cavity milling
- Electronics: 5G heat sink fabrication
Selection Guide:
For Aluminum:
- Recommended: 3-flute, 45° helix
- Avoid: TiN coating (causes built-up edge)
For Stainless Steel:
- Must use: TiCN/TiAlN coated
- Optimal: 4-flute design
FAQ Section:
Q: HSS vs carbide end mills?
A: HSS offers better toughness for interrupted cuts, while carbide provides longer wear resistance.
Q: How to identify worn end mills?
A: Look for:
- Burr formation
- Surface finish degradation
- Unusual noise during cutting
Maintenance Tips:
- Use coolant for stainless steel
- Reduce feed rate when machining hardened materials
- Store in original packaging to prevent edge damage

Our company specializes in manufacturing and customizing a wide array of cutting tools, dedicated to boosting clients' production efficiency and slashing manufacturing costs. We offer comprehensive tool solutions tailored for various cutting materials, encompassing carbon steel (approx. HB225 hardness), alloy steel (HB225~325 hardness), pre-hardened steel (up to HRC45 hardness), quenched steel (HRC40~61 hardness), and cast iron. These solutions cater to diverse cutting needs, including straight cuts, curved cuts, L-shaped cuts, groove cuts, internal arc cuts, external arc cuts, T-shaped cuts, drilling, and threading.
Our carbide cutting tools excel in processing the aforementioned steel types, delivering exceptional performance with a precision tolerance of just ±0.02mm. This ensures that our customers can effortlessly achieve professional-grade cutting quality, making us your ideal partner for milling tool solutions.
We can provide customized OEM production services. If our standard carbide milling cutters do not meet your requirements, you can customize the diameter within 0.2mm-25mm, the total length from 50mm to 200mm, and choose flutes of 4F, 5F, 6F, or 8F. You can also add your own logo. Please feel free to contact us for any needs.
